"99 cobra mustang motor and 5speed tranny installed, need help"


  

          

Ok guys, Ive done what im sure a lot of you dreamed of doing. My 93 mark has a 99 cobra drive train successfully installed. Problem is, im gettin no spark. Everything is hooked up with the exception of a few wires, but when i try to turn it over, im not even gettin a fart. The Cobra motor and tranny are wired up with the original ecu and wiring harness, all the appropriate changes were made to make this computer believe it still has a mark motor in it.

I replaced the crank sensor with a new one, and that wasnt the problem.
I suspect that I made need a cobra wiring harness and comp, but i wana try to avoid this if possible.

The crank turns and the starter works and fuel pressure is good, its just im gettin NOTHING for a spark.

BTW if anybody was thinkin about doin this, DONT... It took atleast a half a summer to do it with a full time job and alota will power. But u must b creative and like to fabricate ure own things.

I NEED the experts on this one, this car must turn ova!

Took me a year to put the 04 in mine Well the crank position could do it but if you replaced it then I would check you coil packs and wires again.

Also check the cam position sensor. Obviously check the things we always forget about, like fuses and relays.

I converted to COP and ran into the same problem, turned out to be the manner in which I wired the COPs and was nothing else.

What wires do you not have hooked up?

Is the engine grounded? Make sure it has a good ground! How are you testing for spark?

ill check the coil packs and wires again,
but the cam postioning sensor i forgot about completely, and fuses and relays are good tho,i checked those already, There is one plug i have no place to plug it into and its got me puzzled, if i got some time to cram over the wiring diagrams i could probably find what it goes to. And other than the tubes that go to the egr pipe/cat everything is basically plugged in correctly. THe engine is definitely grounded, i put in all new negative battery cable one to motor and one to body. I am testing for spark by somebody watchin for spark on the DIS system (one of the coil packs)with the wire off.

If my crank is turning, then i def shouldnt have a problem with a ground right?

So you are living proof that the mark viii wiring harness can work?

besides things not being plugged in all the way, or wires being damaged, how else could i put in the wiring incorrectly for my spark problem, Im doing some hard studying now to go over things, but is there anything else i should b lookin for?

Yup the harness will work. But the way I look for spark is to use a spare spark plug with wire attached, I then hold the spark plug threads to a good ground on the engine and see if I see spark. It the quickest way I know of and by using the engine for ground you thus know it has a good ground.

wow very clever, ill definitely do that, thanks for the good news on the ecu, i figured a dohc motor to dohc motor swap could keep the same comp, ill let u guys know how it comes out. I have some wiring diagrams, but does any body have some really good pics of the wiring harness layed out on a mark viii motor handy, i did a search, but friendly angles dont seem to be kicking around in this forum.

ok i have the weekend to make this car run, and all i need is a spark. Everything is hooked up, the motor, the transmission, the rear end, and all the wires are plugged in, i checked the crank sensor again and the cam position sensor again, nothing seems to b wrong, and ive continuously checked for spark a number of different ways including the ones suggested and ive had no spark. Ive searched and found out that the harness could be bad for the cam position sensor, but does anybody else have ideas. Ive checked the EDIS brackets and every wire is free of damage and are hooked up properly. I checked the fuses and the grounds and there is nothing wrong there? I have a ford technician friend coming over tomorrow but any guesses from the experts on this forum?

My attack tomorrow includes using a volt meter to see if the brackets are gettin power, i kno these coil packs are good cuz they worked for the mark before i did the swap.

Ive done many searches on the forum and noticed that the harness to the Cam position sensor can go, could this cause no spark?

Also if my DPFE Sensor was disconnected could that cause my car not to start?

Exactly how much re-wiring was done? If the car does not detect the fact that you are in PARK, it will NOT fire up. The original trans harness and MLPS need to be hooked up. Its part of the anti-theft system.

wait so wat exactly do i need to do to solve the problem u just told me?

Ive got the reverse lights hooked up, and i took the pins that needed to b spliced together and ran a small crimped wire between them, supposively that did something with the neutral safety switch so i could start it in neutral? Basically i followed the directions exactly from the TCCOA forum techinical article.

Would the antitheft system let my car turn the crank and but just not fire the spark plugs? I need ure help guys, ive gotta get this car moving before i go back to RI

Mr John is the mighty wise one on this I bet. Stupid question, but have you tried starting it in Neutral?

I think it will NOT cranks if MLPS is MIA, but your situation is unique. I dont think this will help, but it might not hurt to read and give you some idea. I am going to keep mining for info...

http://www.markviii.org/htdocs/dc/dcboard.php?az=show_topic&forum=21&topic_id=58872&mesg_id=58872&listing_type=search



Just to clarify, in case I read over it, the only harness changed was the trans? Main engine is the same, right?

By the way, did you ground the engine? (it cranks over, but the engine itself needs a SOLID ground, I ran a batter cable right to the back of one of the heads)

Ive only tried to start the car in neutral, cuz i have the neutral safety switch bypassed just like the tech article from tccoa. I also did a lot of research and thinking, which ruled out that the MLPS is not my problem cuz it wouldn't even try to crank if it wasnt wired correctly.

I read the posts on ure links and it gave me some more ideas, I appreciate all ure help searching.

The only harness changed was the transmission harness. The 99 cobra engine and 5 speed tranny will b running off the original mark viii ecu and harness. Ive been told this should work no problem with just alot of CE lights. Also the engine is rigged up to the max to think, its still a mark viii motor. Making all the necessary mods. Same fuel rails, same coil packs with the EDIS brackets. and same sensors etc. Interesting to know, almost all of the sensors, like the crank sensor and cam position sensor for example are the same part for the 99 cobra and the 93 mark. I just cant generate a spark, but im gona make sure my wiring harness is solid where it meets the CPS and im gona run a voltage meter everywhere, and im gona make an additional ground on top of the others to the back of one of the heads to the body like u suggested.

Keep the help coming guys, i wana show u guys vids and pics to reward u guys for all the effort, I just wish one of u guys was close so u could help me slap this guy into shape, i have one ford technician, but hes s a 5.0 guy so he hates my #### lol

The cam position sensor will not cause the car not to start if it bad/un-pluged. HOWEVER the CRANK position sensor is another story. But I though you had checked that. Its at the bottom front of the engine, passenger side. Make sure its hooked up or you will NOT get spark. If any sensor is at fault, its this one, but again I thought it was checked - just making sure.

If u guys think of anything else let me kno

Your swap is no mystery; I've done a few and have helped out in a number of them besides tuning. It's hard to trouble shoot without seeing the vehicle. Take some pics of the wiring and post them. The Mark EEC and harness will run the vehicle; this is the easiest of the swaps. You do have to extend some wires. The two main bundles that run across the Mark intake have to be opened up and split in order to run the wiring properly. This involves cutting and splicing. The IAC, TPS, crank sensor and right side coil pack have to be lengthened. So any of these places there could be a break in the wiring. All these should be soldered and not crimped. Then you need have the EEC reprogrammed to turn off the trans function, make the proper changes for the new engine.

wow, you were the guy i was lookin to talk to. Yea mark eec and harness are being used. I did make those splits like u said, i remember doin that very well. They are crimped for now, but will b soldered eventually, when i start giving more cosmetic effort to the engine bay. If the eec is not reprogrammed yet to turn off the trans function, what happens? I've planned to get this computer reprogrammed soon after i got it runnning, but do u think this is why my car wont make a single spark?
I'm taking pictures in about a half an hour, of every view i can. How do u post pictures?

photobucket.com and copy/paste the URL line here, with a return before and after it. Once you get to the site, you will know what to do.

ok i have quite a few 4 megapixel quality pictures of the motor and wiring. Quite possibly every angle, so it should be pretty easy to see everything. Ill throw these pics on photobucket.com tomorrow. And for the throttle cable pieces and cruise control pieces and/or anything else missing, i kno about it , i havent put them back on yet. Also i kno the
plug cover on one of the valve covers isnt bolted down. but anything else u c feel free to yell at me for.

the motor wires aren't quite neat cuz i was testing wires just before

Nice car. But honestly the images are REALLY blurry. My head hurts!! lol

What fuel rails are you using?

Buy the way, looks A LOT like my setup!

yea im seein the similarities, looks really good.

Im using the fuel rails and fuel lines from the mark viii. I had to modify the fuel rails a bit to fit, but fuel pressure is good and there is no crimped points in the lines or rails.

The reason for this was i found out that the cobra had a returnless fuel system and i wanted to keep the car thinkin it was still a mark viii, as much as possible. Also because im using the mark viii eec and harness, i didnt wana make anything complicated. Basically kept this the rule of thumb (it still thinks its a mark viii).

I cant get new pictures till the weekend, cuz im in RI during the week for classes. Is there anything that needs explaining or descriptions.

For the record.




The ECM does NOT NEED to be reflashed to turn off auto tranny functions. My 94 has been running the stock ECM with a T45 for well over 2 years now.


Are you really gonna leave the shifter in that location? It's not that hard to extend the linkage to make it fit right. Also, What are you doing for the ecm harness? I built a custom harness to relocate it to the rear package rack in the trunk.

well never thought the computer needed to be reflashed, someone on the forums told me 2, but regardless its still not giving me a spark, ill b checkin voltages this weekend if i get the time.

As for the shifter, there are NO available shifter box extension parts available or in production, sccoa.com are sold out as well as mn12performance.com, ive called and emailed both. But the way u c it in those pictures is not the way i have it, the center console is gone now and i have a custom composite based piece that finishes the edge of the dash and i have plenty of room to use the shifter now, but cosmetics still arent to worried about when the car wont even turn over lol.

As for the wiring harness, i also consider that to be a cosmetic thing. Ill eventually redo all the wires so that they rap around the firewall back side of the car.

The Ecm harness will probably end up under the dash cuz i made room, or ill steal that idea from u, sounds clean, but for now, i just WANA SPARK!.

I understand the spark problem.......



But if I were going to all this trouble...I'd attempt to make it look as stock as possible. My opinion tho. I made my own shifter extension for my 94.

Sorry I've been pretty busy so I wasn't able to get back to this thread. The pics really do me no good, they are too blurry and don't show where you spliced the harness. I realize you are just trying to make it work right now but as forethought, the cleaner it is the easier it is to work with.

Now what I would do is go back and check all your butt connectors to make sure they didn't come loose or not making contact such as crimped on the insulation vice the wire. Then I would start checking for resistance from the connectors that you extended all the way back to the pin in that big square 42 pin connector C118 behind the driver's shock tower, to find your break. You can see it in the top right corner of my pic.

If the Mark engine ran fine before you pulled it and this Cobra engine ran before you installed it, then it's something that you changed. There is no real difference between a Cobra engine and a Mark engine so if it wasn't for the changes needed for the newer style connectors and placement of the actuators and sensors it would be a plug and play situation. The Mark EEC will run the Cobra engine but it won't be correct without a reprogramming. You have actuators and sensor on the new engine that run at a different impedance than your Mark. The Cobra components operated with a faster MHz EEC than the Mark. The Cobra has totally different heads requiring different spark and the list goes on.

As for the fuel rails; you can go with aftermarket for the Cobra that are set up for return style like in my pic.

94m5, you are wrong or totally clueless in telling him he doesn't need a reprogramming. You apparently don't know anything about how an EEC works or it's multiple strategies that depend on input from the trans unless reconfigured.

Your vehicle may be running without reprogramming which it will but it will be running very poorly compared to one that is set up correctly with a reprogramming. I suppose you've also removed the CEL light so it doesn't annoy you like most others that have gone this route.

Well my 04 equip Mark runs great without re-programming, but then I am ODB II - not sure if that makes a difference. I used all the stock 04 sensors I could because they were new. The only thing MIA is the knock sensors - they are not even hooked up. I also have a CE light that comes on start-up, but throw no codes - figure that one out. No knock sensors, IMRCs or cats..... Also the spark plug gap is the same for the terminator class engine with 764 and no blower @ .054 With blower or colder you can go down to .035

What I am getting at is that the problem maybe in the trans end. I almost wonder if using a non-altered trans harness and using the stock MLPS to rig it up will work. The trans harness will not be needed to be hooked up to the actual trans I believe.

Why do this? Then we can rule out one end or the other.

Also, have you removed the plugs? If you have been cranking this thing over and dumping fuel in there you may have flooded the engine or fouled the plugs. If you have a spare plug that is CLEAN pull it and do the spark test again incase the original plugs are really that bad.

We really need to start ruling things out for sure. But reprogramming is not necessary to get it running. We are not getting spark and there are a few factors that can cause that, we need to find the one before we move onto reprogramming, etc...

It could be possible that, although you've done the trans harness mod's needed, you still could have bypassed something to tell the engine to crank, but it still isn't see'n a Park/Neutral signal which isn't allowing it to spark. In a "normal" scenario, you wouldn't even get the engine to crank, but now that you've re-pinned/spliced/jumped wires, I bet you've bypassed the "no crank" feature and now you're still not getting the "neutral" safety the car is looking for. If you have access to a Snap-On Scanner, that would help you tremendously, that was you can plug it in and the scanner will tell you what gear you're in(obviously you don't have the auto) and than you can be SURE that you wired it write. Call your local auto shop and tell them you problem, and ask if you can give them 50 bucks and see if they can stop by, or see what they would charge you if you towed it over there. This will rule in/out the issue with the trans harness telling the computer its in Park/Neutral.

The 99 Cobra motor has COP ignition, you are using the Mark VIII coil pack/wire ignition and stock Mark ECU, perhaps you didn't set this up correctly somehow?

I thought I read he is using coil packs with plug wires. As far as I read the main harness was never altered. I thought the same thing at first since I myself have swapped my 96 to COP and did it wrong - but I got spark, just not the correct spark.

If you did make ANY changes to the main harness, let us know (again).

edit:
And I dont know how it works, but I mentioned this before and will mention it again. The ant-theft system also goes through the MLPS. But I think it prevents crank... but like mentioned above maybe there are two outputs, one foe crank and one for spark.

First of all, you guys are awesome, its like having a ton of different gear heads thinking for me around the clock.

im gona try to answer everybodies post. here it goes:

I definitely want to make it look cleaner and easier to work with, will do when i have the time.

What exactly is a butt connector?, humor me cuz i forget.

Yea and ill check resistances with the volt meter right?

Next I didnt extend any connectors to the pin in taht big square 42 pin connector C118 behind the driver's shock tower. Why, how, and for wat reason do i do that?

Yes the mark engine ran fine before i pulled it

The cobra engine only has approximately has under 9000 miles on it, so it should have ran before no prob.

What changes did u make for the cobra engine? I just replaced any cobra sensor with the original or new mark sensor.

Where can i get the aftermarket fuel rails for the cobra set up for return style like ures.

I will get the eec reprogrammed, but how and where, and should i just wait for it to turn over first?

i will take really good pictures of my MLPS and stock harness as it exists now so u guys can rule out if thats the problem

I may have not set the Mark VIII coil pack/wire ignition and stock Mark ECU correctly, other than just pluggin everything in like it was before, Im not sure how to change any of it. All i did was bolt back on the EDIS brackets, plugged in their corresponding plugs from the harness and plugged the wires on them and through the spark plugs and wires in on the motor.

I didnt make any changes to the main harness, all i did was unplug everythign, flop them ova to the side, did the motor and tranny swap, then flopped them back ova and plugged everything in

How ever i had to split up the cover on near the tb to get those sensors to reach enough, like lonnie did, then add a wire spliced in to reach the sensor on the intake tube. And thats it basically

In advance, id like to thank everybody for there enthusiasm, you guys really kno ure stuff. im gona put some serious time into gettin some neat clean pics for u guys soon. Plus i have a ford tech friend (more a 5.0 guy) and a mechanic friend ( doesnt like anything modded) and ill try to keep pushing them for help. Where are u guys from. Im located in Hull, MA and Narragansett, RI

Yourís may run but it isnít running correctly or at its optimal capability. Like I pointed out in my other post thereís a multitude of parameters that should be changed due to the different heads and intake flow characteristics and burn rates. You have codes, the device you are using just isnít able to pull them. If you had it reprogrammed those would be eliminated. You havenít thrown any hard codes so youíve been lucky and it hasnít gone into the limp home mode.

You also went from an EEC V system to another EEC V systemís sensors so thereís no problems with interchangeability. Where as with his there is with some sensors.

As for your theory of the Anti-Theft system and MLPS; the A/T system does not go through the MLPS. It has its own Starter Interrupt Relay that will cut voltage to the starter solenoid. This is inline of the of the ignition switch directly to the starter solenoid, circuit 32.

The MLPS is used to control the starter solenoid, circuit 33. When placed in Park or Neutral it closes the switch in the solenoid so that battery voltage can be sent to the starter motor when the ignition key is turned.

Nether one of these have anything to do with spark, they only control the voltage to the starter. His vehicle is turning over, he just doesnít have spark. So like I said he has a problem with his wiring in the harness that he has modified.

And yes his should start up and run without a reprogramming of the EEC.

Can anybody tell me what these wires are for and do i need them for the cobra motor?

They came from the 93 Mark engine and the two threaded pieces were screwed into the block under the intake manifold, and the plug ran to the back of the motor towards the fire wall, right where the heater hoses are.




And Lonnie, I PMed u for some of ure advice.

Also I can give u guys 7megapixel clear images of anything you need to see, just tell me what specifically you want to see for images of the motor and wiring.

Also does anybody know how I could start to test for resistance from the coil packs back to the wiring. Also i found a wire or wires that have been nicked slightly in the top right hand side of the engine bay. Could this be my break in the spark wires?

Those are knock sensors. I never put mine in and the engine does not sound like its knocking at all - and yes I know what it sounds like since I did once own a 73. But you should get those installed.

Take a photo of the damaged wire please.

Ya, I am on here all day, literally. I have net access at work. I manage a tanning salon so I have lots of free time, then I go home, where I have more free time! LOL

Pics are good Be careful with those coil packs! High rate discharge capacitors is what they really are, one wrong move and ouch!!!

Ok here are some pics:

The first 3 are just views of the engine bay








This next picture is of a plug that I havent found a place to plug it into and what its for. Next is a picture of the plug and its location.
Its directly under the fuse box and it comes out of the largest roll of wires that stream out of that fuse box.






The last three images involve the wire/wires that i found that were scuffed bad by a drill. You cant actually see the wire's cut, but the wire thats scuffed is from the wires that are wrapped completely with black tape all around, and its scuffed at the top. You can see it a bit in the pic. The first pic is the close up and the other two are for the location its in.







Please let me kno if theres any more pics needed, ill b back at the garage until this car is done.

Come on dude! You covered the plug end in tape! LOL... I have no clue, need to see the plug. Anyway, the ones under the fuse box are almost always critical to starting the car. But what I find odd is the black tubing on it, that is not anything I have seen on my 96, but may have been factory. But I need to see the plug and maybe I can tell ya what its for or if it was something that was added later. Or maybe its the variable steering assist harness.

The harnesses in back that you took pictures of look okay. One goes to the trans I think. You would really have to pull back the covering better to look for exposed wires. But the main engine harness looks intact, and thats a good thing.

So when ya can, get a better pic of the tape covered one so I can be more sure. And pull back its covering just a bit so the colors can be better seen.

Thanks!

That mystery plug. By chance its not Light Green with Pink stripe and Teal with Light Green stripe? Cause that would be anti-theft.... I think.

John might know!!!!!

haha my B,
If it helps I think the colors were green with orange stripe and green with black or purple stripe. I'll get you clear uncovered pics of that plug inside and out first thing tomorrow. THat would b awesome if I just found out that that plug was the reason it wasnt sparking.

Good news on that wire, thanks, Ill fix it tomorrow as well.

actually I think you are right with those colors you guessed.

After lookin at it with the original pictures it looks like teal with white stripe and the other wire was light green with pink/orange stripe.

Either way ill have really nice pictures with wire colors and uncovered plug pics

I'd like to add.....you say above that "the drill scuffed some wires", I just want to make sure that when this happened, the battery wasn't connected because you may have shorted something out.

naa the battery wasn't in the car, and that wire has been fixed. I just wish i could solve this wiring harness problem so I could get a spark and drive this car.

Looks to me like the Coolant Level Sensor Connector. I believe it should connect to your overflow tank, but I'm not 100% sure. I found it by looking through the assortment of pigtails they have on RockAuto.

Hope this helps,

Like he said, could be coolant level sensor. Does that teal have a light green line on it? TO me, it looks like it does. I know you said it did not, but can ya double check please? LG and TEAL blend well so it can be hard to see.

Thanks guys, Ill plug it in first thing today, but yea there is no stripe on that wire, i spent a lot of time confirming that yesterday.

So now there is no plug in my engine bay that's not plugged in. Too bad it doesnt start. I'm gona probably start a post in the electrical section because it's more appropriate about testing the wiring harness to see why its not giving me a spark.

The problem is that your 1993 Mark has an EEV-IV PCM designed to use coil packs and your engine has COP ignition. The '93 doesn't use a Cam Position Sensor because it uses a lost spark method, in other words it fires two cylinder simultaneously - one on the compression stroke and one on the exhaust stroke. So it only use a Crank Position Sensor.

Note in the pictures from Lonnie, that he has coil packs and plug wires. As I see it, you will either need to use the ignition system from the Mark VIII engine, or go with the Gen 2 PCM and do some rewiring. It would seem to be easier to use the older style ignition and look into any other sensors or components necessary to convert the engine from EEC-V to EEC-IV. My engine is a 1996 Cobra, so it was a straight forward install.

Also, you can't just reflash to older PCM modules like you can with the EEC-V.

Did you read any of the posts ?

butt connectors = crimp connectors = bad connection IMHO.

He is NOT using COPs right? Did I miss something? Read it over and over....

I keep reading that all he did was swap the harness right over, no mods to it.

No COPs, he extended some wires and changed come connectors. Then he used butt connectors, or crimp style.

Ouch. No crimps, no butts. Solder all the way! I learned this with my cam sensor long ago.
